PRESSURE-CARBURETER.

Specification of Letters Patent.

Patented Get. 12, 19315.

To all 1o/tom 'it may concern. A Be it known that 1, CLAUDE MARIUsl CAR- nun, a citizen of thelepublic of France, and

resident of Paris, France, (post-office address 124 Rue Mnilmontant,) have invented anew and useful Pressure-Carburetor, which carbureter is fully set forth in the following specilication.

The present'invention relates to pressure carbureters permitting of supplying the engine with a mixture of air carbureted simply by contact on leaving the sprayer, constituted by air under pressure with vapors of fuel by mixing. l

pressure carburetor forming the subject of the invention is'illustrated, by way in the accompanying drawing,

charged in which* Figure 1. is a vertical section through the whole device. detail. Fig. 3 is a part-sectional view of a further detail.l

The sprayer is constituted by three concentric nozzles 1, 2, 3, and of these the nozzle l communicates through the medium of the conduit 4 with the chamber 5; the nozzle 2. communicates through the medium of the conduit 6 having'a greater cross-sectional area than the conduit 4, with the same-chamber; and the nozzle 3 communicates through the medium of the conduit 7 with the cylinder 8. In the latter there moves the piston 9 controlled by a manually-operated oscillating arm 10 and provided to this end with a projection 11 actingon the rod of the said piston; the same arm controls simultaneously the rotation of-a plate 12, to thezstem of which it is suitably xed, said plate being arranged in the chamber 5 and formed with two openings 13, 14 adapted to register-alter- 'natelywith the conduits 4, 6 according to the position of the arm 10; according to this position also, the piston 9. shuts or opens the larger (16) of the twosoriices 16,17 formed at the point Where th'ecpnduit -7 opens into and gas the nozzle 3 into the engine.

Fig. 2 is an elevation lof av F ig. 1, corresponds to that of operation at hlgh speed, that is to say the cam 11 on the arm 10 being out of alinement with the stein of the piston 9, the latter uncovers the orifice 16 and the opening 14 of the plate 12 vregisters with the conduit 6. The air which enters the tank 19 under pressure through the plpe 20 is charged with the vapors of fuel by Y passing.A through the said tank, after which it passes successively through the 18, the cylinder 8, the i conduit 7, to the sprayer ffseapes through y At the vsame time, fuel passes successively through the pipe 22, the chamber 5, the opening 14 .in plate 12- and vthe conduit 6, to the nozzle 2 and on leaving the sprayer, mixes with the fuel-charged air. For slow running, the arm 10 is displaced in such a manner that the cam 11 is brought into line with the roc` the piston 9, so as to move the latter in and ' wardly and thus close the orilice 16 at the same time that, owing to the angular displacement of the plate 12, the chamber only communicates with the conduit 4 through the opening 13. In such instance, the quantity of fuel-charged air passing through the reduced orifice 1T, is exactly proportionate to the reduced quantity of fuel passing through the conduit 4 having a restricted cross-sectional area; the fuel then passes through the central nozzle 1. A propellerl or screw 23 is arranged above a perforated sheet metal plate 24 to prevent im purities from penetrating and causing wear on the parts, and is rotated at a suitable speed so as' to insure the illing of the `cylinder with air. For very accelerated running, the butterfly valve 25 is closed and through the opening 26 air is supplied under a presorifices 16, 17, and thev Sura it may be ,used for l said tank; a cylinder having pipe leading bureter operating exclusively by the simple mixture of air and fuel at the outlet of the sprayer, operating in this case as a fuel atomizer, using, to this end, the above described device.

The gaseous ixture. being under presd feeding lamps and lanterns of the vehicle on which the carbureter is in use for supplying or feeding the engine.

What I claim is:

ll. A pressure carbureter comprising, in combination, a sprayer consisting of three concentric nozzles; a fuel tank; a compressed air-supply pipe leading into the bottom of a passage leading therefrom 4to the outer nozzle; a pipe leading from the top of said tank to said cylinder, to supply fuel-charged air from the former to the latter; a piston Working in said cylinder to control the delivery of the charged air therefrom through said passage to said outer nozzle; a controlling 'chamber' having a pair of passages leading therefrom to the intermediate and inner nozzles; a member rotatably mounted in said chamber and formed with a pair of orifices adapted to alternately open and close the second named passages; a fuel-supply pipe leading from said tank to said chamber; and means for operating said piston and said rotatablymounted member.
